Latest Patents

Ryo Taura's latest patents include "Multiheight contact via structures for a multilevel interconnect structure." This invention describes a method for forming contact openings that extend to sacrificial layers located at different depths. The process involves sequentially exposing a greater number of openings in a mask layer through iterative alternation of trimming a slimming layer over the mask layer and performing an anisotropic etch that recesses pre-existing contact openings by one level. In one embodiment, pairs of electrically conductive via contacts and electrodes can be simultaneously formed as integrated line and via structures. Another embodiment allows for the formation of encapsulated unfilled cavities in the contact openings through non-conformal deposition of a material layer. The electrically conductive electrodes can be created by replacing portions of the sacrificial layers, followed by the formation of electrically conductive via contacts on these electrodes. Additionally, electrically conductive via contacts extending to electrodes located at different levels can be provided with a self-aligned insulating liner.

Another patent by Ryo Taura is titled "Multiheight electrically conductive via contacts for a multilevel interconnect structure."
